When when Marco Rubio implode?

[Mehmentum]

I think Rubio is in less danger of imploding, an in more danger of never really catching on in the first place. 

Despite getting a ton of favorable media coverage after the debate, the two polls that we have from after the debate show little to no increase in support for him.  It might very well be that there just isn't much of an appetite for a candidate like Rubio anymore.
